This man is Edward Eliot Kramer, 51.
He's one of the founders of the DragonCon science fiction and fantasy convention - and he's in jail right now, accused of child molestation.
The story actually starts more than a decade ago, to 2000, when he was first arrested and accused of sexually abusing three teens in Georgia, according to the Atlanta Journal-Constitution.
At the time, he was considered physically incapable of being put on trial because of the spinal and respiratory problems I can only assume are the reason for the Darth Vader-ish look he's starting to sport in this photo.
Well, turns out he wasn't too physically incapable to be caught in a hotel room in Connecticut with a 14-year-old boy last year.
So all bets are off now - he's being put on trial for those original charges.
Gwinnett County District Attorney Danny Porter says Kramer befriends single moms... then uses his relationship with them to molest their boys, according to wsbtv.com. He says any victims should reach out to him.
DragonCon fans, don't worry - Kramer hasn't been involved in the convention since the original charges back in 2000, according to comicsbeat.com.
